Frequently Asked Questions About Plate and Frame Filter Plates
Q1: How does a plate and frame filter plate work?
Solid plates and hollow frames alternate in the plate pack. Slurry fills each frame cavity, cloth on the plate faces retains the solids, and the cake builds up inside the frame until the pack is opened for discharge.
Q2: When is plate and frame the better choice over recessed chamber?
The frame gives a large, open cavity, which suits fibrous, stringy or coarse crystalline feed that would bridge in a narrow recess. It is also the classic format for polishing and fine clarification duties.
Q3: What temperature and pressure are supported?
Polypropylene plates work from 80 to 120°C depending on the material, and glass-fibre reinforced options reach 120°C. Operating pressure goes up to 16 bar and can be customised.
Q4: How is the plate sealed?
Sealing is by compression gasket or integrated sealing edge. Combined with a machined plate surface, this keeps the pack tight at working pressure.
Q5: Can they be used in food or pharmaceutical plants?
Yes. The plates are made from non-toxic, odourless food-grade materials, which makes them a common choice for edible oil, juice, dairy and API filtration.
